Story

You can fill out an adoption application online on our official website. Meet Rambo – The Resilient Gentle Giant Rambo is a handsome Mastiff with a heart as big as his frame! He’s the stronger and more energetic of the two brothers — his sibling Kane is already in rescue with him — and this boy is full of life. Rambo can be strong on leash, so a prong collar and an experienced handler will help him shine. Once he gets his zoomies out, he settles right into a calm, low-key companion who loves attention and affection. Rambo and Kane’s story is heartbreaking but full of hope. The two brothers were abandoned in California by their breeder or owner and ended up in a shelter, facing the euthanasia list. Both were suffering from mycoplasma pneumonia and were incredibly sick for over a month. Thanks to love, care, and good nutrition, these boys pulled through and are now healthy, happy, and ready to begin their new lives. Rambo deserves a forever home that will give him structure, love, and a soft place to land — something he’s never truly had before.

You can fill out an adoption application online on our official website.Bear – The Gentle Giant Looking for His Forever Home Arizona Mastiff Rescue | azmastiffrescue.com#AZMastiffRescue #RescueOneUntilTheyreNone #AdoptDontShop #GiantBreedRescue #MastiffLove Meet Bear, our incredibly sweet 1–2-year-old Mastiff boy who survived more than any dog should. Bear was abandoned out in Maricopa and left to fend for himself. Scared and defensive at first, this gentle soul was rescued by a kind Good Samaritan who quickly realized he was all heart. Once safe, Bear showed that he’s fantastic with kids (ages 5+ due to size) and dog friendly. He’s calm, respectful, gentle, and absolutely loves human affection. This big sweetheart enjoys going for walks and has that classic “gentle giant” personality we all adore. Important: Bear can climb a chain-link fence, so he requires a secure block-wall yard for his safety. Bear is truly a gem — a soft, loving boy who just wants to be part of a family. Whoever adopts him will be getting an incredible companion with so much love to give. If you’re looking for a kind-hearted, gentle Mastiff to complete your home, Bear is your boy.
